We loved the Sanctuary House! It is centrally located, yet located off of a busier street, so you get the best of both worlds - a quieter alley street but seconds within reach to cafes, restaurants, shops, taxis, public transportation, etc.
The clean studio is well-appointed, with touches of Thai art and decoration. The queen bed is very comfortable, and there's even a futon for an extra guest. A sizable desk, shelves with guidebooks, and large closet helped us organize ourselves. There's a kitchen with a microwave, electric water kettle, stove, and fridge. We only used the fridge, but had we stayed longer, I'm sure we would have started using the kitchen more. The bathroom features a stand-up shower with a shower curtain and good water pressure.
Evan is a very dependable host- he is very quick to respond through various communication platforms (phone, WhatsApp, Line, etc). He answered my questions efficiently and thoroughly throughout various times during the day. He is a very thorough host who prints out extremely helpful tips on how to get to the apartment, where to eat, how to travel around Bangkok, etc. After such a positive experience , we have already recommended the Sanctuary House to our friends and family for its location, value, cleanliness, and comfortable accomodations; we can't wait to stay in one of Evan's Airbnbs again when we come back to Bangkok!
